The 35-year-old American fashion designer and Project Runway judge says he's interested in launching an athleisure clothing range, which would include jersey tops for men and women.
Speaking to Marie Claire in a live vlog, which was aired on their social media page on Tuesday, he said: "I would be very interested in doing an athleisure line because I like the ergonomic lines on the body and how they're cut, and I think it would really work well in jerseys and yoga gear and workout gear, men's and women's."
However, the fashion mogul - who was named the Creative Director of the long standing men's clothier Brooks Brothers in 2014 to modernise the brand and evolve their womenswear collection - said he has not worn trainers for 15 years around New York, and would only don a pair when in the countryside.
"No sneakers in the workplace. On the train it's fine - you can have a working girl moment.
"I have sweatpants that I wear, I wear t-shirts in my own world."
